Help with System.AccessViolationException

[fernandozago]

Hello Guys,

Im receiving this exception. And none of this exception stack is related with my code...

I can't find the problem...

Edit: I cant get to throw consistently. But I noticed that the problem occurs when i have the dashboard open on "Activations by Type" page....

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
